Pressure washing block paving can completely transform its appearance — but without re-sanding afterwards, you’re leaving the job unfinished.
When block paving is cleaned, the kiln-dried sand between the joints is washed out along with the dirt, moss and weeds. That sand isn’t just cosmetic — it plays a vital structural role. It locks the blocks together, prevents movement, and helps distribute weight across the surface.
Without proper re-sanding, blocks can begin to shift, edges can sink, and gaps become the perfect environment for weeds and moss to return quickly. Water can also penetrate more easily beneath the surface, potentially leading to longer-term instability.
Professional re-sanding ensures the joints are completely dry before fresh kiln-dried sand is brushed in correctly and compacted. This restores the integrity of the surface and helps protect your driveway or patio from premature wear.
The result isn’t just a clean surface — it’s a stable, longer-lasting one that continues to perform as it should.
